Observation of an electric quadrupole transition in a negative ion: Experiment and Theory
C. W. Walter, S. E. Spielman, R. Ponce +4
The first direct experimental observation of an electric quadrupole (2) transition between bound states of an atomic negative ion has been made. The transition was obse…
PyLCP: A python package for computing laser cooling physics
S. Eckel, D. S. Barker, E. B. Norrgard +1
We present a python object-oriented computer program for simulating various aspects of laser cooling physics. Our software is designed to be both easy to use and adaptable, allowin…
Magic Wavelengths of the Yb Intercombination Transition
T. A. Zheng, Y. A. Yang, M. S. Safronova +4
We calculate and measure the magic wavelengths for the intercombination transition of the neutral ytterbium atom. The calculation is performed with th…
Quantum Blackbody Thermometry
Eric B. Norrgard, Stephen P. Eckel, Christopher L. Holloway +1
Blackbody radiation (BBR) sources are calculable radiation sources that are frequently used in radiometry, temperature dissemination, and remote sensing. Despite their ubiquity, bl…
Predicting quasibound states of negative ions
M. S. Safronova, C. Cheung, M. G. Kozlov +3
We demonstrated the accurate prediction of a quasibound spectrum of a negative ion using a novel high-precision theoretical approach. We used La as a test case due to a recent…
Stern-Gerlach Interferometry with the Atom Chip
Mark Keil, Shimon Machluf, Yair Margalit +12
In this invited review in honor of 100 years since the Stern-Gerlach (SG) experiments, we describe a decade of SG interferometry on the atom chip. The SG effect has been a paradigm…
Precision measurement of the and quadrupole moments in Lu
R. Kaewuam, T. R. Tan, Zhiqiang Zhang +3
Precision measurements of the Lu and quadrupole moments have been carried out giving and , respect…
Nuclear spin-dependent parity-violating effects in light polyatomic molecules
Yongliang Hao, Petr Navrátil, Eric B. Norrgard +5
Measurements of nuclear spin-dependent parity-violating (NSD-PV) effects provide an excellent opportunity to test nuclear models and to search for physics beyond the Standard Model…
Measurement of the molecular dipole moment and the hyperfine and -doublet splittings of the state of thallium fluoride
Nathan B. Clayburn, Trevor H. Wright, Eric B. Norrgard +2
We report high-precision measurements on the thallium fluoride hyperfine manifold of the () state. This state is of special interest because it is ce…
Confinement of an alkaline-earth element in a grating magneto-optical trap
A. Sitaram, P. K. Elgee, G. K. Campbell +3
We demonstrate a compact magneto-optical trap (MOT) of alkaline-earth atoms using a nanofabricated diffraction grating chip. A single input laser beam, resonant with the broad …
Competition between Factors Determining Bright versus Dark Atomic States within a Laser Mode
Bryan Hemingway, T. G. Akin, Steven Peil +1
We observe bimodal fluorescence patterns from atoms in a fast atomic beam when the laser excitation occurs in the presence of a magnetic field and the atoms sample only a portion o…
Detection of missing low-lying atomic states in actinium
Ke Zhang, Dominik Studer, Felix Weber +10
Two lowest-energy odd-parity atomic levels of actinium, 7s^27p 2P^o_1/2, 7s^27p 2P^o_3/2, were observed via two-step resonant laser-ionization spectroscopy and their respective ene…
Optical clocks based on the Cf and Cf ions
S. G. Porsev, U. I. Safronova, M. S. Safronova +4
Recent experimental progress in cooling, trapping, and quantum logic spectroscopy of highly-charged ions (HCIs) made HCIs accessible for high resolution spectroscopy and precision…
Calculation of higher-order corrections to the light shift of the -- clock transition in Cd
S. G. Porsev, M. S. Safronova
In the recent work [A.~Yamaguchi et. al, Phys. Rev. Lett. {\bf 123}, 113201 (2019)] Cd has been identified as an excellent candidate for a lattice clock. Here, we carried out compu…
Branching fractions for decays in Ba
Zhiqiang Zhang, K. J. Arnold, S. R. Chanu +3
Branching fractions for decays from the level in Ba have been measured with a single laser-cooled ion. Decay probabilities to , and $D_{5/2…
